Placeholder – Poll Question:

Would you consider using inkjet printing in your production?

A – YesB – NoC – Maybe

Why inkjet?

Campaign specific/personalized

Country versioning

Traceability

Now thousands of food items

printed every day using

this technology

The Benefits

Efficient use of consumablesEconomic short runsCost per print = for 1, 100, 10,000No time for set-upFaster market responsePrint on demand –Just-in-time customisationRapid introduction of new designsSubstrate agnostic

Changing the distribution model

Print & Distribute Distribute & Print

The Hurdles

Using fully edible materials

Managing quality for industrial printing

Contamination risks

Complex mixture

Materials control performance

Challenge of consistency

A typical digital ink…

Liquid carrier

Binders/ bulk

matrix

Rheology

modifiers

Functional

materials

Colorants

Surfactants

Adhesion

promoters

Other

additives

Pressure wave created inside ink chamber

Drop “forced” through the nozzle

Drop in flight

Coalescence of drop, small satellite drop

Drop landing on substrate

The Process

Billions of drops produced every minute

Reliable process key

Controlled drop formation and spread

Ink not 100% of the solution

Industrial adoption needs system integration

Contamination introduction points

Optimization for application

Highly irregular

Absorbent vs non-porous

Challenge of color

The substrate

High surface energy

Need for high quality

Approved materials

The challenge of substrate

Wetting behavior on capsule substrate

Initial formulation

+ surfactant

Bleed difference

Pitting/pinholes

Use of ImageXpert

The challenge of capsules

Characterizing impact of non uniform wetting

Placeholder – Poll Question:

Have you bought edible ink or an inkjet printed food/pharmaceutical item?

A – YesB – NoC – Possibly without knowing

Testing

Heavy metals

Micro contamination

AdulterationVery little safety documentation from suppliers

Tested available products used for birthday cakes, cookies and candies, and found heavy metals and micro contamination

Risk of micro-contamination
